arXiv:2605.24930v1 Announce Type: new Abstract: Transformer-based LLMs achieve strong results on many language tasks; however, long inputs remain challenging because context windows are finite, and prefill latency and memory grow rapidly with prompt length. Flat token-stream processing and chunk-based retrieval can therefore spend substantial computation and context budget on text unrelated to the query. Offline-indexed RAG additionally introduces external storage and index management overhead, and typically appends retrieved evidence as raw text, increasing prefill cost and latency. H^{2}MT m
The continuous drive to improve large language models (LLMs) capabilities, particularly in handling longer contexts and reducing computational overhead, necessitates new architectural innovations like hierarchical memory transformers.
Improving the efficiency and context window of LLMs directly impacts the scalability and real-world applicability across numerous AI-driven tasks and industries.
This innovation proposes a method to process long inputs more efficiently and reduce prefill latency, potentially extending the practical limits of LLM usage without the overhead of external RAG systems.
